Filed June 1S, 1965, Ser. No. 464,012 1 Claim. (Cl. 19159) The inventionrelates to cards used in textile industry land more particularly tosliver coilers for these machines.

In the textile industry, coilers are known which include a can providedwith an inlet and a mechanism for coiling the sliver into the canarranged above can. However a coiler of this type does not allow cardsto be used in conjunction with other machines operably related to thefurther processing of the sliver. In addition, with these coilers, it isnot possible to form a stock of sliver at each card.

Attempts have been made to overcome the above mentioned disadvantagesbut none of these prior proposals have been successful.

Applicants have found that such disadvantages can be overcome by theemployment of a coiler comprising a can having a sliver inlet opening inthe bottom thereof, a mechanism for laying a sliver in the can mountedon a base beneath the can adjacent to the inlet opening, and a devicefor feeding positively in an upward direction a sliver mounted in thecoiler.

The object of this invention is to provide means ensuring operation ofthe card in conjunction with other machines operably related to thefurther processing of sliver.

An important object of the invention is also to insure a sliver stock atthe card.

Further objects and advantages of the invention will become more readilyapparent to persons skilled in the art from the following detaileddescription and annexed drawings and in which drawings;

FIGURE l'is a front view partly in elevation and partly in cross sectionof the coiler embodying the present invention,

FIGURE 2 is a top plan View of FIGURE 1,

FIGURE 3 is a View in side elevation of the coiler shown in FIGURE 1,

FIGURE 4 is a diagramamtic view in elevation showing the coiling of thesliver inthe can, and

FIGURE 5 is a view looking in the direction of the arrow A shown inFIGURE 4.

The coiler consists of a can 1 (FIG. 1) provided with a sliver inlet atthe bottom thereof. A turntable 2 is mounted beneath the can andprovided with an eccentricallly located opening 3 for the passage of asliver and intended for coiling the sliver in the can 1. A trumpet 4 andpositively rotated rolls 5 are mounted on the turntable 2 and functionfor the positive feed of the sliver in an upward direction. In order topermit the oper-ation of cards in conjunction with other machinesoperably related to the sliver processing such as for instance drawingframes, the can 1 is provided in its upper part with a sliver outlet.The turntable 2 is rotated through a worm and worm wheel 6-7 mounted onshaft 8 of card condensing rolls 9, and through -gear 10 meshing withthe toothed periphery of the turntable 2.

For coiling the sliver according to a desired pattern,

for instance a hypocycloid, a reciprocating movement is imparted to thecan 1 by means of crank mechanism 11-12 driven by the shaft 8 throughbevel gears 13-14. More particularly, the can has a reciprocatingmovement along a circumference that is to say by a movement along acircumference during which the line connecting two points of the canalways remains parallel to the line connecting the points in anyposition of the mechanism. The can 1 is arranged relative to theturntable 2 with an eccentricity as denoted at a. The rolls 5 are drivenby bevel gears 15, 16, and the bevel gear 16 is mounted in a housing 17provided with an axial opening 18 for the passage of a sliver 19.

To prevent displacement of sliver coils relative to the can 1, the canis provided with a sliver braking device 20. The coiling of sliver iseffected as follows:

The sliver 19 comes from the condensing rolls 9, moves about guide bars21, 22 (FIG. 4), Passes through the opening 18 in the gear 16, throughtrumpet 4 and is grasped by the rolls 5 which feed the sliver in anupward direction. The sliver is passed through the opening 3 in theturntable 2 which, being set in rotation, coils the sliver into the can1 in shape of a hypocycloid. Next, the sliver is removed from the can 1and forwarded to other machines for subsequent processing.

Thus the present invention elects coiling of the sliver into the canfrom the bottom thereof and provides for the accumulation of a sliverstock at the card whereby the cards may be used in conjunction withother machines for sliver processing.

The invention is not to be confined to any strict conformity to theshowings in the drawings but changes or modifications may be madetherein so long as such changes or modications make no materialdeparture from the spirit and scope of the appended claim.

What is claimed is:

1. A coiler for cards and sliver machines employed in the textileindustry, comprising a can adapted to execute a reciprocating movementalong a circumference, Said can having a sliver inlet opening in thelower portion thereof, means operably related to the can for preventingdisplacement of sliver coils relative to the can, a turntable beneaththe can with the can being disposed eccentrically respecting theturntable, means for coiling the sliver in the can mounted on theturntable in close proximity to the sliver inlet opening, means mountedin said coiling means for positively feeding the sliver in an upwarddirection into the can through the sliver inlet, a driven shaft, a rstdrive connection between the driven shaft and the turntable forimparting rotary movement to the turntable, a crank mechanism operablyconnected to the can, and a second drive connection between the drivenshaft and the crank mechanism, for imparting a reciprocating movement tothe can.
